Immersed spheres of finite total curvature into manifolds

Andrea Mondino and Tristan Rivière


We prove that a sequence of possibly branched, weak immersions of the 2-sphere 𝕊2 into an arbitrary compact Riemannian manifold (Mm,h) with uniformly bounded area and uniformly bounded L2-norm of the second fundamental form either collapse to a point or weakly converges as current, modulo extraction of a subsequence, to a Lipschitz mapping of 𝕊2 and whose image is made of a connected union of finitely many, possibly branched, weak immersions of 𝕊2 with finite total curvature. We prove moreover that if the sequence belongs to a class γ of π2(Mm), the limiting Lipschitz mapping of 𝕊2 realizes this class as well.
